Question

我有一台手提电脑,有一张照片可以上载到网络服务器。问题在于:如何建立国际商业行动,停止上载? 这里是我法典的一个要点:

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];

NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];

NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"
--%@
", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name="userfile"; filename=".jpg"
"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: binary

"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"
--%@--
", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];

Thanks, Coulton!

我认为,这将回答你的所有问题,而且还要回答:

它包含信息飞跃、实例的飞跃,并使用Asyncrhonous,从而阻止了贵方国。在该网页上,我还就发送数据的问题与你想要做的事情完全一样进行了会谈,但我建议从上读到数据,因为你将通过其他事情与你交谈。
